Abstract

A method of using Raman Spectra for determining the progress of a graft polymerization reaction is disclosed. The method entails (a) measuring at the beginning of the reaction and at a plurality of time intervals in the course of the reaction, continuously and on-site, the Raman spectrum in the wave number range of 100 to 4000 cm<SUP>-1 </SUP>of one or more of the monomers and/or polymers entailed in the reaction and of at least one internal standard and (b) recording the spectra and (c) adding reaction partners necessary to the reaction continuously and/or discontinuously and (d) calculating the change in concentration of the monomers and polymers by comparing the spectra of the monomers or polymers with the internal standard.
